Boston University study finds evidence of chronic traumatic encephalopathy (or CTE) in a staggering 110 of 111 brains of deceased former NFL players. There's tremendous "selection bias" in the brains, warns a lead researcher -- BU examined only 111 of some 1,300 brains of players who died after 2008, and many of these brains came from a player's family, some in accordance with the player's wishes -- but even if none of the others showed evidence of CTE, the resulting percentage would still dramatically exceed what you find in the general population. Note well, also, that a lot of these players had long retired before the era of the 300-pound-plus offensive lineman, meaning we can no longer blame the size of the players. We have to blame the game.

Alec Mento's *Penny Rants* books help you relive the horrors of the last 14 years of American politics, but with an improbable optimism and (per Kirkus Reviews) an "acerbic flair" and "a talent for distilling complex ideas into quickly digestible parts."
